Part of this deformation is recorded at the Xauen and Tofiño banks in the southern Alboran Sea. Using swath bathymetry and multichannel seismic reflection data, we identified different stages and styles of deformation. The South Alboran Basin is made up of Early Miocene to Pliocene sedimentary layers that correlate with the West Alboran Basin depocenter and are dominated by E‐W trending folds and thrusts. The Xauen and Tofiño Banks first recorded the phase of extension and strike‐slip movement during the slab retreat, followed by the phase of compressional inversion since the Tortonian and are now structured by tight folds, thrusts, and mud bodies. This study proposes that the Banks were located on the southern‐inherited Subduction Tear Edge Propagator (STEP) fault related to the westward migration of the Alboran domain during the Miocene. The STEP fault zone, acting as a boundary between the African block and the Alboran block, was located along the onshore Jebha‐Nekor fault and the offshore Alboran Ridge and the Yusuf fault zone. Thick‐skinned and thin‐skinned shortening occurred when slab retreat stopped, and inversion began. The present‐day style of the deformation seems to be linked to a decollement level made of undercompacted shale on top of the Ghomaride complex | Descripción: | 25 pages, 14 figures, 1 table.-- Seismic reflection and bathymetric data collected during the MARLBORO and SARAS cruises are stored at SISMER and Seanoe (SEA scieNtific Open data Edition) (https://doi.org/10.17600/11480100, https://doi.org/10.17600/12450090, and https://campagnes.flotteoceanographique.fr/campagnes/12000010) | Versión del editor: | https://doi.org/10.1029/2019TC005885 | URI: | http://hdl.handle.net/10261/211179 | DOI: | 10.1029/2019TC005885 | Identificadores: | issn: 0278-7407 e-issn: 1944-9194 |
